How to connect AWS elasticache redis from Node.js application ?

Answer 1

You're connecting to Redis. The fact that it's a managed AWS service is not really that important in this respect.

So, use a Node.js package that implements a Redis client interface, for example:

• redis
• node-redis

Answer 2

You can use the package ioredis and stablish a connection like this

 const Redis = require('ioredis')
 const redis = new Redis({
 port: 6379,
 host: 'your-redis-host',
 connectTimeout: 10000 // optional
 });

Answer 3

You can try connecting using ioredis.

var Redis = require('ioredis');
var config = require("./config.json");
const redis = new Redis({
 host: config.host,
 port: config.port,
 password: config.password, // If you have any.
 tls: {}, // Add this empty tls field.
});
redis.on('connect', () => {
 console.log('Redis client is initiating a connection to the server.');
});
redis.on('ready', () => {
 console.log('Redis client successfully initiated connection to the server.');
});
redis.on('reconnecting', () => {
 console.log('Redis client is trying to reconnect to the server...');
});
redis.on('error', (err) => console.log('Redis Client Error', err));
//check the functioning
redis.set("framework", "AngularJS", function(err, reply) {
 console.log("redis.set ", reply);
});
redis.get("framework", function(err, reply) {
 console.log("redis.get ", reply);
});
